Epidemiology and Recurrence of Sigmoid Volvulus: Analysis of Health Insurance Claims Data in Japan.

ABSTRACT:

Objectives

Sigmoid volvulus (SV) is rare in Japan, and most studies have been limited to small numbers or case series reports. We aimed to explore the incidence, risk factors, and recurrence rates of SV in Japan using community-based health insurance claims data.

Methods

We used health insurance claims data from the Toyama Prefecture from April 2018 to March 2022. Individuals aged ≥ 40 years who had no diagnosis of SV (International Statistical Classification of Diseases, 10th Revision) in 2018 were included in our study. Patients who were newly diagnosed with SV in 2019 were identified. The annual incidence, risk factors, and recurrence rates of SV within 2 years of the first endoscopic reduction were evaluated. Poisson regression analysis was employed to identify risk fact
